Description
Technical field
The present invention relates to a kind of conveying of sheet that is used for and open device by printing machinery.
Background technology
Disclose a kind of page or leaf control device that page or leaf is opened transfer cylinder that is used for by DE 41 13 478 A1, in this device, three scanning elements are arranged in the zone at grippers edge, and the page or leaf that is used to survey on the cylinder is opened leading edge.Can control page or leaf like this and open position on outer surface of cylinder.The signal of scanning element can flow to the analytical calculation device of stable state by the rotation transponder.
At the device of opening marginal position according to a kind of page or leaf that is used for controlling on the conveying cylinder of DE 43 23 091 A1, a capacitive character edge sensor and the inductive rotation transponder that high-frequency range is interior are set.The inductance of the electric capacity of sensor and a coupling coil constitutes a passive oscillation loop, this loop can with the active oscillating loop coupling of the analytical calculation unit of a stable state.
DE 198 53 417 A1 disclose a kind of counter-rotating cylinder that has the jaw type grippers, in this cylinder, open at page or leaf according to the type of jaw type grippers and to constitute a page or leaf on the leading edge and open the disappearance sensor.Lose from the jaw type grippers if page or leaf is opened, then this signal of sensor changes.
The page or leaf that discloses a kind of photoelectricity fence form in DE 197 07 657 A1 is opened sensor, and wherein, light beam outwards sends perpendicular to cylinder axis from the position that page or leaf is opened conveying cylinder inside.If page or leaf is opened and to be maintained in the grippers and to have minimum length, the opening that light beam passes cylinder wall is mapped to page or leaf and opens.
Open sensor device according to the page or leaf of DE 197 07 660 A1 and constitute with the light curtain, wherein, the receiver of the light emitters of emitting parallel light bundle and correspondence is arranged in the transport path both sides in the page or leaf Zhang Fanzhuan zone between storage reel and counter-rotating cylinder.Can check by the light curtain whether the lateral edges that the page or leaf that floats is opened exists certain constantly.
Disclose the device that is used to measure pressure between cylinder by DE 233653 A1 and DE 103 21 360 B3, in these cylinders, under liner, arranged a sensor film or in a recess of the outer surface of a cylinder, arrange a sensor.If stock enters in the gap between the cylinder, the state when not having stock specific pressure mutually can change, and this can determine by the variation of sensor output signal.
These solutions according to prior art only are used for existence or the position that the page or leaf on definite cylinder is opened.Be used for that leading edge is held and all the other positions require to measure the distance that page or leaf is opened delivery element by the blowing and/or the conveying device of being opened by the page or leaf of free delivery of bleeding.
DE 197 30 042 C2 disclose a kind of device that page or leaf is opened delivery of controlling, and in this device, survey the physical location that page or leaf is opened by the sensor of contactlessly working of a fixed-site.After comparing with nominal length, the executive component of blowing and/or air extractor is regulated like this, makes page or leaf open to paste reliably and is placed on the outer surface of cylinder.
DE 198 10 239 A1 disclose the camera surveillance device of a kind of page of Zhang Hangjin.Page or leaf during the video camera of fixed-site produces and carries is opened contour images.Handle the TP of determining that page or leaf is opened according to image.Relatively come to determine by predetermined-TP with the deviation of ideal situation.Determine the regulated quantity of executive component according to these comparing datas, this can prevent reliably that page or leaf from opening and contact with guided plate or air blast track.
The shortcoming that page or leaf with fixed-site is opened the solution of sensor is, measured value is only in little time range or available in the angle range of cylinder or roller.
